I have been trying to get a perfectly working S17Pro back online after a failed braiins upgrade. The unit is basically DOA at this point. I saw another post with the same symptoms as mine. After the upgrade, I can ping the unit for about 1 minute tops, and then it disappears. I can get to the braiins login screen and it will not let me log in before it goes MIA.
I have tried every conceivable SD card upgrade or downgrade I can with zero success. I do not think the SD slot is reading at this point.
 
I have tried the BOS toolbox uninstall and get connection attempt failed. Win Error 10060.

Any other ideas? I think the Braiin OS bricked my board. But I want to see if anyone is aware of any other way to wake up the unit. Thank You
